O lo matou RE o se malosi galue koluse-fesoʻotaʻi sooupu, Faʻaaogaina i le pipiʻi faia e hydroxyl polyurethane, natura poʻo gaosia paʻu, e sili ona lelei faʻamalosia malosi i le paʻu ma le cab ia faʻaaogaina i resin, antioxidant, plasticizing sooupu, mamafa-maaleale ma isi. mafai ona faʻaaogaina o crosslinker nai lo BAYER's Desmodur RE.
Lua-vaega pipiʻi tatau ona faʻaaogaina i totonu o le applicaable vaitaimi pe a maeʻa tuʻu i RE. O le umi o le vaitaimi talafeagai e le gata e fesoʻotaʻi ma le polymer mea o le pipiʻi, ae faʻapea foi ma isi vaega talafeagai (pei o le resin, antioxygen, plasticizer, solvent, ma isi. Pe a latalata i le vaitaimi talafeagai, masani ai ni nai itula poʻo se tasi aso faigaluega, pipiʻi Ua atili ai ona faigata ona faʻagaioia, ma e vave ona tulaʻi mai le viscosity mulimuli ane, ua avea ma jelly le mafai ona toe faʻafoʻi. 100 lelei pipiʻi, Hydroxyl polyurethane (Polyurethane account mo le lata i le 20%), RE fualaʻau 4-7. , O lo matou RE e faia 4-7.
Teuina o Meaai:
Faʻamolemole teu i le uluaʻi faʻamau faʻamau i lalo o le 23 ℃, o oloa e mafai ona faʻasaoina mautu mo le 12 masina. E matua nofouta i le maʻi sili; o le a gaosia carbon dioxide ma ura insoluble i le tali atu i le vai. Afai o le faʻaalia i le ea ea poʻo le malamalama, o le a faʻatelevaveina suiga lanu, ae o le aoga gaioiga o le a le afaina.
